Jameis Winston, QB, Florida State

The ongoing debate as to whether Winston or Marcus Mariota is the draft's top quarterback could last until the first selection is made on April 30, or it could be settled during the combine.

All eyes will be on the Florida State standout, as he will be heavily scrutinized by both the media and league scouts. While Winston is a tremendous talent on the football field, he comes with some serious off-field concerns, and his combine interviews could have a significant impact on his draft stock.

As it stands right now, Winston is in the favor of Tampa Bay Buccaneers head coach Lovie Smith and could be heavily considered at No. 1 overall. Adding to the speculation of the quarterback going No. 1 overall, the Buccaneers recently released last year's starter Josh McCown, according to Pat Yasinskas of ESPN.com.

Interviews won't be the only determining factor in Winston's draft status, as his offseason workouts must impress scouts. After throwing 18 interceptions in 2014, the quarterback will need to prove his accuracy and decision-making skills can remain consistent heading into the NFL.

Winston is expected to be a full participant at the combine, according to Natalie Pierre of AL.com.

Maxx Williams, TE, Minnesota

There may not be a clear-cut first-round tight end this year, but if anyone at the position will be selected within the draft's first 32 picks, it will be Williams. However, if the Minnesota standout is to make that thought come to fruition, he'll need a tremendous combine performance.

Williams is known for his athleticism, soft hands and solid frame (6'4", 250 lbs). He was a huge factor in Minnesota's offense in 2014, hauling in 36 passes for 569 yards and eight touchdowns as a sophomore. Due to his budding skill set, it appears as though Williams has enormous upside going forward.

One reason the tight end may slip to the second round is his inexperience as a blocker. While he's a versatile pass-catcher and does show some physicality, he'll need to prove he has the strength and basic knowledge of becoming a viable in-line blocker at the professional level.

Offenses that utilize tight ends in the slot in a spread formation could jump at Williams early in the draft; however, if he doesn't prove he can be relied upon as a blocker, his suitors could be limited.

Landon Collins, S, Alabama

Collins is in the unique position of being rated far higher than any other safety prospect in this year's draft. Due to several teams with early picks in need of help in the defensive backfield, it could be conceived Collins will be a top-10 selection in 2015. However, he must solidify his status at the combine.

A versatile player with a growing skill set, Collins was a cornerstone of the Alabama defense in 2014. Capable of producing in all facets of the game, he racked up 102 total tackles, three interceptions, seven passes defensed, 4.5 tackles for a loss and one forced fumble in 14 contests, according to CFBStats.com.

Scouts like Collins' blend of a solid 6'0", 222-pound frame and good athleticism. He is a hard-hitting player who can deliver some bone-crushing hits, but he also possesses fluid hips and can adjust nicely when in coverage. A sure tackler, Collins is extremely reliable when he's able to attack downhill in run support.

Displaying these qualities at the combine will virtually assure Collins a high draft pick.
